Need help, ok we put a smarty jr on our 2010 6.7 no deletes ran great tons of power and good mpg, then we did the deletes with 5'' turbo back had the ME software installed on the smarty and put it on the truck and it just dosn't have the same power as it did befor we did the deletes and Edit MPG. someone told me that when we did the deletes and disconect the battery it may have re set the ECU any help would be great

 

All I will say is to make sure you follow the directions to a tee on the website for disconnecting the correct devices and re-load the software to the truck. If there are any errors, the SMarty will recover and re-flash the ECM to stock mode and start over. Not any other uploaders can do that.
